The Plainview Independent School District on Friday announced several staff changes across its elementary campuses.

The changes stem from the retirement of Edgemere Elementary Principal Angie Valdez, who will retire at the end of the fall semester.

The 1975 Plainview High School graduate began her career in education as a kindergarten assistant at Thunderbird Elementary, according to a letter released by Plainview ISD Superintendent H. T. Sanchez Friday afternoon. Valdez spent seven years at Thunderbird before earning her degree and teaching certification.

She joined Edgemere 12 years ago as an assistant principal and became principal in 2015.

Leslie Richburg, current principal at Highland Elementary, will replace Valdez as Edgemere's principal. According to Sanchez's letter, Lacie Jones – current assistant principal of Edgemere - will become assistant principal of Highland Elementary and Deborah Alcozer, current special programs coordinator for the district, will replace Jones.

Richburg began her career at Plainview ISD in 2000 as an English and physics teacher at Plainview High School. She served in that position for 13 years, including 10 years as sponsor of the school's student council, before moving to Coronado Middle School in 2014. Richburg – a graduate of Texas A&M University – served Coronado as a math interventionist for one year before taking on the role of assistant principal of Highland in 2015.

Jones, Richburg's replacement, has been assistant principal of Edgemere since 2016. Prior to her time in Plainview, the Pampa-native worked in the Lubbock Independent School District as a teacher for four years after graduating from Lubbock Christian University in 2012 and from Texas Tech in 2010.

Alcozer, who will replace Jones at Edgemere, is a Plainview High School and WBU graduate. She started her career with PISD as a teacher at Thunderbird where she spent four years before moving to Edgemere Elementary for a year. Alcozer has been at Central Office for about five years.

In her retirement, Valdez plans to take care of her father and let "her brain rest."
